Swift 4:

var textField: UITextField?

func configurationTextField(textField: UITextField!) {
    if (textField) != nil {
        self.textField = textField!        //Save reference to the UITextField
        self.textField?.placeholder = "Some text";
    }
}

func openAlertView() {
    let alert = UIAlertController(title: "Alert Title", message: "Alert Message", preferredStyle: UIAlertControllerStyle.alert)
    alert.addTextField(configurationHandler: configurationTextField)
    alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler:nil))
    alert.addAction(UIAlertAction(title: "Ok", style: .default, handler:{ (UIAlertAction) in
        print("User click Ok button")
    }))
    self.present(alert, animated: true, completion: nil)
}
